Easy steps for battery life preservation

This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.

The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.

I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS

widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

Don't download the anaimation sub-app. update on the hour (or 2) instead of 15 -30 min.

I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%

Would anyone suggest Advanced Task Killer or Juice Defender?

There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.

I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!

Going nuts!! Battery...

Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???

can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?

I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.

I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.

Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.

here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......

I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.

Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update

I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping

my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.

Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.

Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!

flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.

I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.

Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.

get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Shuts down when battery low, but not dead

I'm having issues with my phone shutting off when the battery meter is low but not dead.The indicator will be yellow and still shut off. When I power it back on and plug it in, its completely dead .
is the phone innacurately reporting the battery percentage?

Sounds like the battery isn't conditioned correctly. There are apps in the market to help with that.

Look in battery configs battstats prob in /data/system and prob elsewhere
Sent from my HTC VLE_U using xda premium

Arent there other ways to condition the battery with an app? i heard like running the phone to empty and then fully charging? any advice?

The problem with running it empty is the battery will never fully discharge because the phone is reading the stats incorrectly.

can you recommend any specific app for this? do you have to be rooted?

You'd have to look at the requirements per app but I do believe you need root.

Your phone isn't going to report one thing, but "believe" a different thing because of bad battery stats. A Google employee has already debunked "conditioning" your battery by deleting battery stats; the phone uses it for reference only, not to make any decisions, especially when to shut down. Something is wrong with the battery itself, or your phone, not your stats.
Swyped, not typed, from my Digital Brick

It might be better over time. Had mine for two weeks now, and I had it run out on me three times. First time it shut down at about 13% left on the meter, second time around 8% and this last time at 2%. Good enough for me, but it's annoying if an untampered new phone doesn't report at least somewhat close to real battery-state.
I usually hook it on the charger at 15%-30% (approx 12-16 hours usage) in the evening, and sometimes have a few short charges (25-30 minutes) from the car-charger during the day.

I've never let mine get below 50% since I got it, but I just ran it into the ground with a terminal process ('yes && yes') and it went all the way to 0% and then powered off.

[Q] CM10 not charging past 90%

I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.

Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?

Tonight, in almos 6 hours my battery has dropped around 4% being in airplane mode. I have installed betterbatterystats and i cannot see anything strange

what used up the 4% that is not strange?

I unplugged my phone at around 3am because I rolled over and noticed the notification led blinking. I was at 100% and cleared the notification. Went back to sleep then got up around 5:30am and looked at my phone. I noticed my battery was down more than I expected so I checked the stats. I was down almost 20% in 2 hours 30 minutes. Android OS was at 60% usage with time on a 2 hours 20 minutes. I had sleep assist turned on during the night and I also keep wifi and data on. I've installed Wakelock Detector to see if it will be able to see what in Android OS is keeping my phone on.

fyi. when you charge your phone, the battery starts discharging once the battery is FULL, NOT when the cable is unplugged. However, the battery % will not drop whilst the phone is plugged in,
Therefore, if you charge your phone fully but don't unplug it for hours, it 'may' appear to discharge faster than normal once you do unplug it. (basically the phone will over present it's true charge level).
If you unplug the phone as soon as its fully charged, however, it will appear to discharge more slowly...

The Android battery stats will start the clock ticking from 9am when they unplug their phone, however the battery started discharging 6 hours erlier when he phone was fully charged at 3am... The % then drops much faster than expected as it races to it's 'true' level of charge. This could explain the differences people are seeing in some cases...

actually you are just partially right. the percentage only drops until reaching a trigger level, where it starts to charge again. also in my opinion when the phone is charged and left plugged in it uses the power directly and leaves the battery untouched

Hogwash.
Lithium batteries don't retain a memory.. You can charge them as often as you want... No matter what percentage your at. And if you leave it plugged in it will keep your battery fully charged with a trickle charge at 100...
I'm not sure what wives tales you've been reading.... But not everything on the Internet is true.... So you know.
I read something else around here lately where a guy was saying basically if you plug in at bedtime, you better wake up after a couple hours and unplug.... Or you'll damage your battery. Lol
Anyway.... Charge how ever you feel you need to.... To each their own. But I guarantee your battery will not drain quicker cause you left it charging all night.... That's simply ridiculous.
No offence.

its not hogwash, I think maybe you misunderstood me. I'm well aware lithium cells aren't memory cells. In fact, check my post history I posted as much in a thread of someone asking 'how best to first charge their moto G'. So if this is what you thought I meant, fairplay.
However,
Someone clarified above there is a 'threshold' level. however, these phones do not 'trickle charge' it's not a car battery. Charging at full amps when the battery is full would damage it, hence it stops charging, starts to discharge, then at some 'threshold level' will begin charging again, it does not trickle charge..
Also, as a matter of fact a friend of mine is an electrical engineer, does small Linux projects and some work on ARM architecture. I first heard about this behaviour when charging whilst on the XDA S2 forum. We tested the charge in the S2 1650mha battery ourselves and found we could get a variety of charge levels all shown as '100%' on the phone, just by when we unplugged the charger. I'm making an assumption this phone behaves the same, however why would it not?
So, all I would say to anyone on this forum. Just because someone has a lot of posts and thanks and 'knows his stuff' , This guy should take his own advice and not believe everything he reads on the internet...
